I have itchy skin every where no dry skin and when it itches it starts to burn and get red but no bumps or rash what is this ?

Well: It gets red and itches then goes away, no rash or bumps. It could be a rash or what is called idiopathic urticaria, release of inflammation due to stress. Oddlly enough sometimes an h-2 bkocker like tagamet for the the stomach can help. It may be allergic reaction or something else and i would not avoid seeing a doctor. I would trey Benadryl (diphenhydramine) at night and tagamet is pretty cheap. Look up idiop.
